Stern rail seats
I ordered the seats from Hunter for my 1995 26 and they made them for me for $650. You will need to know the number of your boat because it will determine if you need aluminum backing plates. Depending on the number of the boat, Hunter added aluminum plates on the inside of the boat so that you can drill and tap into them to fasten the seats in place. Without the plates in place, Hunter will supply them if you ask and you will need to put them in place yourself, drill through and bolt the seats in place. You will need two people at least and you will have to do some bending and twisting of the parts to make them fit. Not rocket science but slow and methodical will get it done.
